Once upon a time, a young lad was born without a bellybutton.
In its place was a silver screw. All the doctors told his
mother there was nothing they could do.
Like it or not, he was stuck with it . . . He was screwed.
All the years of growing up were real tough on him,
as all who saw the screw made fun of him.
He avoided leaving his house . . . thus, never
made any friends.
One day, a mysterious stranger saw his belly and
told him of a monk in Tibet who could get rid of
the screw for him. He was thrilled. The next day,
he took all of his life's savings and bought a ticket to Nepal.
After several days of climbing up steep cliffs,
he came upon a giant monastery. The monk knew exactly
why he had come.
The screwy guy was told to sleep in the highest tower
of the monastery and the following day when he awoke,
the screw would have been removed. The man immediately
went to the room and fell asleep.
During the night while he slept, a purple fog floated
in an open window. In the mist floated a solid silver
screwdriver. In just moments, the screwdriver removed
the screw and disappeared out the window.
The next morning when the man awoke, he saw the silver
screw laying on the pillow next to him. Reaching down,
he felt his navel, and there was no screw there!
Jubilant, he leaped out of bed . . . And his butt
fell off.
The moral to this is:

'Don't screw around with things you don't understand.
You could lose your ass.'
